A DAG (Directed Acyclic Graph) is a type of graph structure that consists of nodes and directed edges, where:

  • Each edge has a direction (from one node to another)
  • There are no cycles — you cannot start from a node and return to it by following the direction of the edges

In simple terms, a DAG is like a flowchart where tasks move in one direction and never loop back.


Why DAGs Matter in Orchestration

In orchestration systems like Lyzr Agent Orchestration (LAO), DAGs play a critical role in defining task flows or execution pipelines. Each task or agent is represented as a node, and the edges define the order of execution.


🛠️ Benefits of Using DAGs in Orchestration

Clear Task Dependencies

DAGs allow you to define which tasks depend on others, making the execution order explicit and easy to visualize.

Parallel Execution

Independent branches of a DAG can run in parallel, improving performance and efficiency.

Failure Isolation

Since each node is isolated and independent, failures can be detected and handled without collapsing the entire pipeline.

Reproducibility

By defining a clear execution flow, DAGs make processes predictable, repeatable, and easier to debug.
